FUEL-FEEDING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 659,200, dated October9, 1900. Application filed April 2'7, 1900. Serial No. 14,630. (Nomodel.)

To a whom it may concern:

Be it known that LTHOMAS ASENCIO, a citizen of the United States, and aresident of the borough of Manhattan, in the city and 5 State of NewYork, have invented a new and useful Fuel-Feeding Attachment, of whichthe following is a specification.

My invention relates to an attachment for feeding fuel in a pulverizedor powdered IO state to steam-boiler and other furnaces.

The object is to provide a feeding device which is complete in itselfand which may be made and sold as an article of manufacture in sizes tosuit the different demands for furnaces,either stationary or locomotive.

A practical embodiment of my invention is represented in theaccompanying drawings, in which 2 Figure 1 isaview of the attachment inside elevation; and Fig. 2 is a top plan view, the hopper and thepulverizer casing being broken away to show the screw feed and rotarybeaters and'blower.

a represents a base common to a rotary motor, a rotary pulverizer, afeed-hopper, and means for forcing the material from the hopper into thepulverizer.

1) represents a rotary motor of any wellknown or approved form-in thepresent instance asteam-turbine. As my invention does not relatespecifically to the particular form of rotary motor, the same isindicated only in elevation and top plan and will be recognized as aform in common use. In

like manner 0 represents a pulverizer of any well-known or approvedform, the form here indicated being that in which the coal is beateninto a pulverized or floured condition by rotary beaters,which havetheir blades so 0 set as to force the matter from the feed end of thepulverizer to the discharge end 11 of the same. The pulverizer 0 alsoacts either alone or in connection with a blower located therein toproduce an air blast outwardly through this discharge-opening d to blowthe pulverized or powdered materialinto the furnace.

The arrangement for pulverizing and blowing the material does notspecifically form a part of my present application and is therefore onlyrepresented in side elevation and top plan.

From the common base a uprise supporting-standards of g h, in the topsof which standards a shaft '0' is journaled, the said shaft 5 5 i beingcommon to the rotary motor and to the rotary boaters and the rotaryblower, (represented as the pulverizer c.)

The casing within which the rotary heaters and rotary blower of thepulverizer are located is supported from the common base a by means oflegs k Z.

The hopper m,- which directsthe coal to the pulverizer, is supported ona bracket n, attached to the end of the pulverizer casing, anda feedingdevice-in the present instance a screw-feed 0, located at the base ofthe hop= per and driven by means of a pulley p from a source of powernot shown-serves to force the coal at a uniform rate into position to beengaged by the heaters of the pulverizer.

The gist of my invention lies in the combination of a motor, pulverizer,and blower in such compact form and so corelated in capacity andoperation that an attachment of a given capacity will furnish thenecessary and uniform amount of fuel elements (powdered coal and air)required for any particular furnace, thus obviating the difficultieshitherto experienced in attempting to secure the proper feed by settingup the pulverizer, blower, and motor, one or more of them, independentlyof the other or others.

My present attachment, being made in the proper proportions andsimplified by placing theseveralimportant parts onacommonshaft, thewhole supported upon a common base, so that it may be shipped intact,assures perfect action, the only requirement from the purchaser beingthe size of furnace or amount of steam required to be generated.

Whatl claim is- An attachment for steam-boiler and other furnacescomprising a rotary motor and a rotary pulverizer and blower arranged tobe actuated by the motor, the said motor pulvel'izer and blower having acommon shaft and being so correlated in capacity and operation that anattachment of a given capacity will furnish the necessary and uniform 5amount of fuel elements required for any paltieular furnace.

In testimony that I claim the foregoing as my invention I have signed myname, in presenee of two Witnesses, this 24th day of April,

THOMAS ASENOIO. Witnesses: v

FREDK. HAYNES, EDWARD VIsER.
